MOUNTING FOR CIRCUIT-BREAKERS.

Specification of Letters Pstent.

Patented Nov. 6, 1917.

Application filed February 2, 1917. Serial Ho. 1482:.

To all whom it may concern:

Be it known that I, NICHOLAS J. CONRAD, a citizen of the United States, residing at Chicago, in the count of Cook and State of 6 Illinois, have invents. a certain new and us c ful Improvement in Mountings for Circuit- Breakers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanyingdrewin forming a part'of this specification.

fly invention relzitesto mountings for circuit breakers, particularly for high tension fuses and switches f The object of the present invention is to provide an" improved form of molmtmg which is compact, requires little room formounting, mu. be constructed st low cost and which a ords ample electrical protection.

y The embodiment which I have illustrated in the accompanying drawings is adapted for either indoor oroutdoor installation. I 'haveillustrated'the some as adopted to mount a fuse of the type shown in the patent to Schweitzer end Conrad No. 1,135,548 granted April 13th 1915,- but it is to be understood that the fuse to be mounted may -85 parallel relation upon a hose which has been made of a length equal to or greater than the length of the fuse or switch." As :1 come quence it has heretofore been found necessary to provide a; s'upportingfrume of considercble extenteither for the mounting itself or for the base of the mounting. This is not only-expensive but also generally inconvenient and in some cases impossible.

My in ention aims to dispense with the 46 necessity for such extensive support and provides a pedestal of such dimensions as to be readily mounted directly upon a'wall or upon any suitable support even though the some he of small extent.

It is to be understood that the mountin ma be placed on any othersupport j' for instance as a frame made of, pi

pedestal is made of suitable configuration to be attached to the pipe. i The pedestal 1 is proyidedwith mpair-of sockets'fi and 7 into which are fastened the ends of the osts or columnsfiend 9 cfin sulation. ese'columns- 8 end 9 'in the embodiment of Figs. 'I' cnd- 2 are 'mcde'" of tubes of insulation preferably of urelctijely strcgi material such as-fiber impregnated wit lUl'lDS are secured in the tubular sockets" 6' and 7 by means of'pins 10 and 11.

. Metal caps.12 and 13 which are provided with tubular sockets 14: and 15 are mounted on the outer or divergent end's of'the columns 8end 9. These socket'members 14: and 15 are secured to'the colu n'msby means of pins 16 and 17 y The caps 11-12 'inay be secured to the up er ends of the columns in a. number of'di erent ways its is well un-- derstood by those skilled in the art, the

sockets and'pins being but one of many ways for. securing this result;- The cap members 12 and 13 are preferably provided with in-'- p wnrdly extending H s 18 and 19 which provide supp rts for t a spring clips 20 and 21 thatembrace'the metallic terminals 22' and 23 of-the fuse 5. The s'prin clip 21 is provided with a stop or support 54 for insuring the correct position of the fpse .5 in the'spzring clips 20 and 21 end for supporting t 6 lower end of the some to prevent-1'10 use 2 of such-6pdimensions as to be readily mounted upon a,

akeli'te- The lower ends of 'the colaxial displacement. Suitable lin'e terminals 26 and 27 are connected to the metal caps 12 and 13 by means of bolts 28 and 29.

The fuse which I have shown is of the type employing a bath of are e tinguishing liquid and movable fuse terinin s adapted to be separated by spring tension upon destruction of the fuse.

The top of the fuse is provided with a removable venting member 30 which is adapted to release the pressure generated 'tact for. the blade is mounted upon the upon violent blowing of a fuse.

Wherev the mounting supports a switch, the blade is pivoted at one end upon one cap member such as 12 and a corresponding conother 13. I have not illustrated the same as the articular form of a switch or circuit brea er employed is immaterial,

In the embodiment of Fig. 3 I employ columns 32 and 33 of molded insulation with surface corrugations for increasing the cree age distance across the surface of the insu ating material. Due to the diverging arrangement of the columns 32 and 33, the corrugations 34 and 35 are substantially at right angles to each other and at substantiall degrees to the vertical.

e mountin is generally set either in the vertical position or in the horizontal position. In either case the corrugations 35 lie at .45 degrees to the vertical and thus -may drain ofi' such moisture or precipitation as i fall upon them equally well in either position. p

The columns 32 and 33 are preferably made of molded insulation and may be of any configuration desired. I have shown the same as of a gradually increasing and decreasing diameter throughout the corrugations.

In the form shown in Fig. 3, the spring clips 20 and 21 which engage the terminals of. the fuse 5' are mounted upon-metallic extensions 36 and 37 which connect the clips with the line terminals 26 and is to. be noted that one size of mounting'may be'employed for different sizes of fuses b providing the proper l ngths of connecting plates 36 or 37 themo vice being to that extent adjustable for mounting different sizes of fuses.

The. fuse 5 illustrated in Figs. 1 and 2 is provided with a shell or casin of glass tubing. The fuse 5' s own in Fig. 3 has a'shell or casing of bakelite or of fiber impregnated with bakclite. Except as to the features above mentioned the embodiment of Fig. 3 is the same as shown in Figs. 1 and 2. It is understood that the fuse 5' is illustrative of any suitable circuit breaker.

which are ting deconstructed umns need not be straight as it is obvious that the advantages of my invention may be secured without a strictadherence to the showing of the drawings. I do not intend to be limited tothe precise details shown and described.

I claim:

1. In combination, a generally rectangular metal pedestal, said pedestal havin tubular sockets with axes lying in substantially the same plane and substantially at right angles to each other, columns of insulat on having their ends resting in said sockets, means for securing said columns in said sockets, caps for said columns, said caps having tubular sockets adapted to fit over the ends of said columns and having substantially flat top surfaces parallel to the base 1n the same plane and extending substan-' tially at forty-five degrees to the plane of the base, columns of insulation having their ends resting in said sockets, said columns having corrugated sides to increase the creepage distance, said corrugations on the columns extending substantially at forty-five degrees to the vertical whereby the nature of the creepage path is unaffected by change in position, and terminal supports mounted on the ends of said column v 3.
